DeShaun Watson targeted Thomas three times and Thomas caught all three for 61 yards, including back-to-back grabs for 31 and 18 yards on Houston’s opening touchdown drive.

But he stood to be the goat after a series of fourth-quarter follies that including a false start, lining up in the wrong spot — even having to run over and ask Watson what to do — and having to burn a timeout.

“I messed up a couple of times and I felt like it would have been on me if we didn’t get that W,” Thomas said.

“He was hearing one thing and doing the opposite,” Watson said. “I had to make sure he was on the same page as me. He did a good job. Some things we are going to fix.”

The Texans joined the 1970 New York Giants as the only teams since the merger to win six straight following an 0-3 start.

McMANUS’ MISSES

McManus’ second miss of the game came after Case Keenum completed an 18-yard pass between two defenders to Emmanuel Sanders on fourth-and-8 from the Denver 45-yard line with under a minute left.

“Terrible kicks,” McManus said. “Even the 62-yarder, it was terrible.”

Broncos coach Vance Joseph blamed himself for the first miss, saying he got greedy. It backfired when the Texans got the ball in Broncos territory and 18 seconds left in the first half and Ka’imi Fairbairn nailed a 46-yard do-over for a 16-10 Houston halftime lead after his errant attempt was wiped away because Joseph had called timeout to ice him.

Joseph said he didn’t try to get closer for McManus’ game-winning attempt because the Broncos had already reached their “line to go” inside the 35.

“I was totally confident in Brandon,” Miller said. “From 62 and 51, my money’s on Brandon. He’s our sniper. He’s our brother. It’s one of the hardest positions in pro sports. Sometimes you just can’t put it through the uprights.”

Said Keenum: “I knew Brandon was going to make it and I still know he’s going to make it when we give him that chance again. I think he’s the best kicker in the league.”

Keenum threw a 5-yard pass to tight end Jeff Heuerman, who had a career-best 10 catches for 83 yards and then running back Phillip Lindsay lost a yard, leaving McManus with a 51-yard attempt.

After the Broncos took a 17-16 lead on Keenum’s 12-yard dart to Heuerman between two defenders, Fairbairn put the Texans back ahead with a 37-yard field goal with 14:06 remaining.

Thomas had started all 114 games for the Broncos since Jan. 8, 2012, when he caught an 80-yard touchdown pass from Tim Tebow on the first snap of overtime to beat the Pittsburgh Steelers 29-23.

This time, he drew loud ovations when he emerged from the tunnel for pregame stretch and again during a video tribute after “The Star-Spangled Banner.”

Outside the stadium, the Broncos put up a giant “Thank you, D.T.” banner at the bottom of a 10-story-high image of Thomas next to one of Von Miller, who said last week it was “super weird” not having Thomas as a teammate anymore.

After Thomas lost the coin toss, Denver deferred and Thomas went right to work, catching consecutive passes covering 31 and 18 yards as the Texans took a quick 7-0 lead on Watson’s 7-yard TD pass to tight end Jordan Thomas .

Watson’s 36th career TD throw was a 16-yarder to DeAndre Hopkins that put Houston ahead 13-3. The only other quarterbacks in NFL history to have 35 or more TD passes in their first 16 NFL games were Hall of Famers Kurt Warner and Dan Marino.

INJURY REPORT

Texans: OLB Duke Ejiofor left in the first half with a shoulder injury.

Broncos: Center Matt Paradis broke his right fibula when Keenum rolled up on him just before halftime. Paradis had never missed a snap in his four-year career and appeared in line for a contract extension with the money the Broncos saved by trading Thomas.

“It’s a huge loss,” Joseph said, “losing one of our captains and a guy who’s played a lot of football for us.”
